Overview

DATA SHEET MOS INTEGRATED CIRCUIT µPD78323,78324 16/8-BIT SINGLE-CHIP MICROCONTROLLER DESCRIPTION The µPD78324 is a 16/8-bit single-chip microcontroller that incorporates a high-performance 16-bit CPU.
The µPD78324 is one of 78K/III series.
The internal capacity is significantly increased compared with the conventional µPD78322.
A realtime pulse unit for realtime pulse control required in motor control, an A/D converter, a ROM, and a RAM have been integrated into one chip.
The µPD78324 incorporates 32K-byte mask ROM and 1024-byte RAM.
The µPD78323 is a ROM-less version of the µPD78324.
Also, It is provided the µPD78P324 as an on-chip PROM product.
Detailed information about product features and specifications can be found in the following document.
µPD78322 User’s Manual : IEU-1248 FEATURES • Internal 16-bit architecture and external 8-bit data bus • High-speed processing by pipeline control and instruction prefetch • Minimum instruction execution time: 250 ns (with 16 MHz external clock in operation) • Instruction set suitable for control operations (µPD78312 upward compatible) • Multiply/divide instructions (16 bits × 16 bits, 32 bits ÷ 16 bits) • Bit manipulation instruction • String instruction, etc.
